Aerodynamic characteristics of parallel two-stage-to-orbit vehicles using two AGRAD-B standard models in supersonic flows
To obtain the aerodynamic characteristics of the interaction of parallel Two-Stage-To-Orbit (TSTO) space vehicles in the cruising regions and separation in the supersonic flow, in the range of M(sub infinite) that is equal to or between 1.5 and 2.5, an AGARD (Advisory Group for Aerospace Research and Development)-B standard model and its half-model were tested using two six force balances. By arranging the two models parallel in the same direction and changing the distance and the angle of attack in the range where alpha is greater than or equal to -12 and less than or equal to 12 deg, six aerodynamic force coefficients were measured and compared with the coefficients for a single model. The aerodynamic forces of the upper second stage plane model varied a short distance behind the shock waves of the partner plane. This indicates that sturdy maneuverability is required for a TSTO, especially for the upper second plane during their separation process.
